Valuations can be done on assets such as investments in stocks, or intangible assets such as patents and trademarks. The absolute value models determine the present value of an asset. The relative value model determines the value based on the market prices of similar assets. Option pricing models are used for warrants, call options, and etc. (Investopedia.com)...
